From The Depths Of Your Nightmares, Furby Returns

1998. Tiger Electronics releases an electronic toy called a Furby, a kind of half-hamster, half-owl, half-hellspawn that becomes an instant hit, a fad the likes of Beanie Babies, Pogs, and Tamagotchi pets.

The Furby “communicates” with other Furbies, in a language dubbed “Furbish,” though they are programmed to eventually speak English.

The Furby then fades into obscurity, returning briefly in 2005, courtesy Hasbro, as an Emoto-Tronic Furby, spawning a number of special interest groups in support of Furbies as emotionally sentient beings.
